Abstract
The parametrization of electrostatic turbulent fluxes in tokamak edge plasmas was investigated. The basic model for the drift wave turbulence simulation was also studied using Hasegawa-Wakatani model. The turbulence is driven by the density and temperature gradients that originally drive the resistive drift wave, and the saturation level is regulated by zonal flows. The results suggest that the parametrization can be a useful numerical tool for self-consistent inclusion of the perpendicular turbulent dynamics for global transport simulations.
